[R] Error -> cannot open file 'specdata/001.csv': No such file or directory; Windows 8, R Version 3.2.1

[Anthoni, Peter (IMK)]

Hi Nikita,

To check whether the files are really there, run the following at the R prompt:

getwd()
list.files()

> *C:/Users/acer/My Documents/specdata/rprog-data-specdata/specdata*

Your working path looks like you either need to set it to:
  C:/Users/acer/My Documents/specdata/rprog-data-specdata
or change your read.csv to:
   df <- read.csv("001.csv")

cheers
Peter
